NOTICE

Notes:

Maximum allowed working pressure is located on the rating plate.

1.The ratings are based on standard test procedures prescribed by the United States Department of Energy.

2.Net I=B=R ratings are based on net installed radiation of sufficient quantity for the requirements of the building and nothing need be added for normal piping and pickup. Ratings are based on a piping and pickup allowance of 1.15.

3.Knight XL boilers require special gas venting. Use only the vent materials and methods specified in the Knight XL Installation and Operation Manual.

4.Standard Knight XL boilers are equipped to operate from sea level to 4,500 feet only with no adjustments. The boiler will de-rate by 4% for each 1,000 feet above sea level up to 4,500 feet.

5.High altitude Knight XL boilers are equipped to operate from 3,000 to 12,000 feet only with no field adjustments. The boiler will de-rate by 2% for each 1,000 feet above 3,000 feet. High altitude models are manufactured with a different control module for altitude operation, but the operation given in this manual remains the same as the standard boilers. A high altitude label (as shown in FIG. A) is also affixed to the unit.

6.Ratings have been confirmed by the Hydronics Institute, Section of AHRI.

7.Knight XL boilers comply with the requirements of CSD-1 Section CW-400 requirements as a temperature operation control. The manual reset high limit provided with the Knight XL is listed to UL353.
